Battery drainage issue in iPhone 16 pro max

I Just bought a new iPhone 16 pro max, 2 months before and after updating iOS 26 the battery became worst it can't last even for half day. Its been more than 1 month of IOS 26 and still battery drainage issue didn't resolve. First time I have updated from Android to IOS and I got disappointed. This make me very sad, after paying a huge amount I can't use my phone for a whole day due to battery issue. Really disappointed

Did you also try to reset the iPhone to factory settings, in case the iOS software caused the issues?

To rule out defective data from the backup, set it up as a new device and test the battery life.

Restore your iPhone, iPad, or iPod to factory settings using a computer - Apple Support


If the battery life is back to normal, restore from the latest backup and check the battery life again.
